hi ,

i have smiple aspx page the i have included ck editor in as follows..

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

</asp:Content>

ck editor renders fine on my aspx page however i am not able to get an instance of editor using any of following syntex...it bascialy gets it undefined..

alert(CKEDITOR.instances[0]);

alert(CKEDITOR.instances["editor1"]);

CKEDITOR.instances["editor1"].on("instanceReady", function() {
alert('instance ready');
});

none of these three work..what am i missing ?..

2. a seprate question - if i want to build drag and drop fetaures in ck editor . so instead of the way it works out of the box ..which is more like u select a area in canvas than u selection a control from tool bar , i want to build ability to drag and drop a control from tool bar to on to the canvas....can some one please point to , how to do this?

thx
